Isolation valves are typically left in either a fully open or fully closed position. A given isolation valve may be in place for many years without being operated, but must be designed to be readily operable whenever needed, including emergency use. Since the alignment stop is missing, it is up to the installer to carefully measure the final location of the slip coupling to ensure that it is located correctly. If there’s a pipe needing cut or bent, we have the equipment to help make it happen.
Pipe Fittings are Piping component that helps in Changes the direction of the flow such as elbows, tees. Changes the size of the pipe such as reducers, reducing tees. Connect different components such as couplings and stop the flows such as Caps.
A tee, the most common pipe fitting, is used to combine or divide fluid flow.Tees can connect pipes of different diameters or change the direction of a pipe run, or both. Available in a variety of materials, sizes and finishes, they may also be used to transport two-fluid mixtures. Tees may be equal or unequal in size of their three connections, with equal tees the most common. In short radius elbow, centreline radius is the same as the nominal size of the pipe or you can say one times the diameter of the pipe.
Pipe fitting product line includes a large number of fitting types that surpass the requirements of this standard. In these special forms, e.g., pipe fittings with spring-back tolerances, the connector dimensions have been adapted to the pertinent standard, so that they can be replaced at any time. There are various pipe fittings available, each with their own unique function. The materials used in plumbing has changed over the years so we’ve made sure that we offer a comprehensive enough range to cater for both old and new installations. You’ll find pipe fittings from leading brands like JG Speedfit, Plumbsure and Fluidmaster that cover a wide range of fitting types. A nipple is a short stub of pipe, usually male-threaded steel, brass, chlorinated polyvinyl chloride , or copper , which connects two other fittings.
This instruction describes the pre-assembly of a cutting ring (SRD…VA) on the stainless steel pipe in the assembly stud and the finishing assembly of the cutting ring in the screw sleeve. Manufacturers such as Victaulic and Grinnell produce sleeve-clamp fittings which are replacing many flange connections. They attach to the end of a pipe segment via circumferential grooves pressed around the end of the pipe to be joined. They are widely used on larger steel pipes, and can also be used with other materials.

Crimped or pressed connections use special fittings which are permanently attached to tubing with a powered crimper. The fittings, manufactured with a pre-installed sealant or O-ring, slide over the tubing to be connected. High pressure is used to deform the fitting and compress the sealant against the inner tubing, creating a leakproof seal. Flange connections tend to be expensive, because of their requirement for precision forming of metal. To make a solder connection, a chemical flux is applied to the inner sleeve of a joint and the pipe is inserted.
Depending on the connection technology and application, basic skills may be sufficient, or specialized skills and professional licensure may be legally required. This fitting differs from a standard cross in that two of the ports have curved inlets. 9000 class fittings are available in only the socket weld type. There are two types of the reducer used in piping Concentric & Eccentric. Generally, crosses are not used in process piping to transport fluid. But forged crosses are common in the firewater sprinkler line.
A reducer can also be used either as a nozzle or diffuser, depending on the mach number of the flow. Dielectric unions, with dielectric insulation, separate dissimilar metals to prevent galvanic corrosion. When two dissimilar metals are in contact with an electrically conductive solution , they form an electrochemical couple which generates a voltage by electrolysis. When the metals are in direct contact with each other, the electric current from one to the other also moves metallic ions from one to the other; this dissolves one metal, depositing it on the other. A dielectric union breaks the electrical path with a plastic liner between its halves, limiting galvanic corrosion.
Unlike metal welding, solvent welding is relatively easy to perform . Solvents typically used for plastics are usually toxic and may be carcinogenic and flammable, requiring adequate ventilation. In drainage systems, it is primarily used to connect horizontal drains to vertical drains. The center connection is generally to the pipe leading to a trap . It must not connect a vertical drain to a horizontal drain, because of the likelihood that solids will accumulate at the bottom of the junction and cause a blockage.
